驾驶员模型对驾驶员诱发振荡评估结果的影响

在飞机设计中,应用不同的驾驶员模型来预测驾驶员诱发振荡(PIO)是避免人机系统出现不良耦合的重要途径之一。以人-机闭环系统为研究对象,以某一电传飞机为例,采用Ⅱ型PIO的开环发生点OLOP评估准则,分别使用增益驾驶员模型和修正Neal-Smith驾驶员模型对人机闭环系统中的PIO易感性进行了分析、评估,对比研究了不同驾驶员模型对OLOP评估准则评估结果的影响。仿真结果表明:不同的驾驶员模型对Ⅱ型PIO评估准则(OLOP)的评估结果有较大的影响,相同驾驶员模型下不同的驾驶员增益对评估结果也有影响。在使用OLOP评估准则时应充分考虑驾驶员模型对评估结论的影响。

Effect of Pilot Model Additions on Pilot Induced Oscillation Assessment Result

In the process of aircraft,a mathematical model of the pilot is usually used to predict aircraft PIO with evaluation criterion.The closed-loop pilot-aircraft system was the research object.Two Pilot Models were examined to category ⅡPIO susceptibility for use with OLOP: the pure gain model and the modified Neal-Smith model.Simulation results show that pilot model were much more influencing about evaluating category ⅡPIO susceptibility of closed-loop pilot-aircraft system.Make suggestions that pilot model is much more important about evaluating category ⅡPIO susceptibility of closed-loop pilot-aircraft system for use with OLOP.
